NERF BigShock Removable Barrel (Elite Dart and Rival HIR)

thingiverse

I wanted to create a NERF MEGA BigShock conversion mod that shoots RIVAL HIR's and Elite sized darts with ease, without requiring any modification to the blaster itself or opening it up. This mod is reversible, as you can simply friction-fit the barrel to your liking. You can also make a similar well-known mod using PEX pipe and a copper PVC coupler, or by taping two cut MEGA darts together - this mod is an alternative to that. The barrel fits snugly inside the MEGA barrel with the dart post intact, disabling the air-restrictor without needing to remove it. This allows air to push RIVAL HIR's and Elite sized darts out of the printed piece. Since the AR is disabled by the printed barrel, dry firing is not recommended. You can push an Elite sized dart all the way in until it stops, and it will fire well. I tested it with EKind waffle head darts, and they seemed to shoot harder than expected. You can also push a RIVAL HIR all the way in until it stops, and it will fire just as well. A layer or two of tape around the bottom of the barrel before the reduction will help create a tighter friction fit and eliminate any air gap between the printed piece and the inside of the original barrel. Depending on how tight you fit it in, you may have more trouble removing it later. If I can get my hands on some brass, I may make a version to fit brass darts in the barrel.
